Abstract: Five lignans and eight triterpenoids were isolated from the aerial parts of Cissus repens. Among them, a lignan, ( + )- isolariciresinol-9′- (2- p-coumaric ) - O-β- D-xylopyranoside (1), was new and its structure was established on the basis of spectroscopic methods and alkaline hydrolysis. Other compounds, ( + ) -isolariciresinol-9′- O-β- D-xylopyranoside (2), ( + ) -lyoniside (3), ( ─) -secoisolariciresinol-9- O-β- D-xylopyranoside (4 ), ( 7′R, 8′S )-4′-hydroxy-3′, 5-dimethoxy-7′, 8′-dihydrobenzofuran-1-propanolneolignan-9′- O-β- D-xylopyranoside (5 ), friedelin ( 6 ), epifriedelanol ( 7), taraxerol-3β- acetate (8), ursolic acid (9 ), 2α-hydroxyursolic acid ( 10), asiatic acid (11 ), niga-ichigoside F1 ( 12 ) and lupeol (13), were found in the plant for the first time.
